ISL43L840IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L840IR-T is a dual-channel analog switch manufactured by Renesas Electronics Corporation, housed in a 16-TSSOP surface-mount package. It operates as a 4:1 multiplexer or demultiplexer circuit with a maximum on-resistance of 750 milliohms and channel-to-channel matching of 120 milliohms. The device supports single-supply voltages ranging from 1.6V to 3.6V. Key electrical specifications include a charge injection of -96pC, off-state leakage current of 4nA maximum, and crosstalk of -100dB at 100kHz. It functions within an ambient temperature range of -40°C to 85°C.
